I'm trying to integrate Firebase Cloud Messaging (I use this code, which is mirrored here) with my existing app.
Relevant codes:
service.php
$msg_id = $_POST['id'];
$title = $_POST['title'];
$content = $_POST['content'];
$msg_date = $_POST['date'];
$author = $_POST['author'];
// insert the message into DB
$sql = "INSERT INTO tbl_message(msg_id, title, content, msg_date, author) VALUES ('$msg_id','$title','$content','$msg_date','$author')";
if ($result = mysqli_query($db, $sql)){
$firebase = new Firebase();
$push = new Push();
$payload = array();
$payload['foo'] = '123';
$payload['bar'] = 'xyz';
$push->setTitle($title);
$push->setMessage($content);
$push->setAuthor($author);
$push->setDate($msg_date);
$push->setImage('');
$push->setPayload($payload);
$push->setIsBackground(FALSE);
$resp = '';
$response = '';
$resp = $push->getPush();
$response = $firebase->sendToTopic('global', $resp);
echo $response;
}
Firebase.php
<?php
class Firebase {
// sending push message to single user by firebase reg id
public function send($to, $message) {
$fields = array(
'to' => $to,
//'data' => $message,
'data' => array("message" => $message));
return $this->sendPushNotification($fields);
}
// Sending message to a topic by topic name
public function sendToTopic($to, $message) {
$fields = array(
'to' => '/topics/' . $to,
//'data' => $message,
'data' => array("message" => $message)
);
return $this->sendPushNotification($fields);
}
// sending push message to multiple users by firebase registration ids
public function sendMultiple($registration_ids, $message) {
$fields = array(
'to' => $registration_ids,
//'data' => $message,
'data' => array("message" => $message)
);
return $this->sendPushNotification($fields);
}
// function makes curl request to firebase servers
private function sendPushNotification($fields) {
require_once 'config.php';
// Set POST variables
$url = 'https://fcm.googleapis.com/fcm/send';
$headers = array(
'Authorization: key=' . FIREBASE_API_KEY,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Disabling SSL Certificate support temporarly
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
// Execute post
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
// Close connection
curl_close($ch);
return $result;
}
}
?>

Sending messages directly from Firebase Console works fine. Now the problem is sending messages via PHP script. Somewhow the server manages to send the message successfuly, e.g:
{"message_id":4732936739964848111}
, and the device receive it:
06-19 09:26:21.590 18604-19560/net.anta40.app.firebasetest E/MyFirebaseMessagingService: From: /topics/global 06-19 09:26:21.590 18604-19560/net.anta40.app.firebasetest E/MyFirebaseMessagingService: Data Payload: {message={"data":{"image":"","is_background":false,"payload":{"bar":"xyz","foo":"123"},"title":"test","message":"mehehehe","timestamp":"2017-06-19 2:26:21"}}} 06-19 09:26:21.600 18604-19560/net.anta40.app.firebasetest E/MyFirebaseMessagingService: push json: {"message":{"data":{"timestamp":"2017-06-19 2:26:21","message":"mehehehe","payload":{"bar":"xyz","foo":"123"},"image":"","title":"test","is_background":false}}} 06-19 09:26:21.600 18604-19560/net.anta40.app.firebasetest E/MyFirebaseMessagingService: Json Exception: No value for data 06-19 09:26:21.720 1098-1098/?
